Most forms that reject your photo do it for one reason: the file is over a size limit. A job portal wants under 200 KB, a visa site under 100 KB, a marketplace under 1 MB. This tool works the other way round from a quality slider: you type the size you need in KB and it finds the best-looking version of your image that fits.
Under the hood it searches for the highest quality setting whose file still lands below your target, and only if that is not enough does it reduce the pixel dimensions, step by step. If your image is already smaller than the target, it tells you so and keeps the original instead of re-saving it for nothing. JPG, PNG and WebP are accepted.
Everything runs on your own device, which matters for the kind of image people usually compress: ID photos, signed documents, screenshots of bank statements. Nothing is uploaded, there is no queue and no daily limit. The honest limit is physics: a very detailed photo squeezed into 20 KB will look soft, because there is only so much information a file that small can carry. When that happens, a slightly larger target usually fixes it.

Frequently asked questions
- Is it really free and unlimited?
- Yes. Everything runs in your browser, so there are no server costs and no limits.
- Do my images get uploaded anywhere?
- Never. The compression happens entirely on your device — your photos are never sent to a server.
- How do you hit an exact KB size?
- The tool searches for the highest image quality whose file size still fits under your target, then downscales if needed.
- What target size should I choose?
- Use the limit the form or site gives you, minus a little margin. For a profile or ID photo, 100 to 200 KB is usually plenty. For a photo that will be viewed full screen, stay above 300 KB.
- Why does my image look blurry after compressing?
- The target was too small for the amount of detail in the picture. Raise the target, or crop the image first so fewer pixels have to fit in the same size.
